1. The forward-curved radial design ensures tight connection between all fan components, and the external rotor motor and impeller work precisely together, laying the foundation for stable and efficient operation.
2. The fan can handle a wide range of air volumes, from 600 m³/h to 6500 m³/h, meeting the air replacement and replenishment needs of various scenarios. Whether exhausting polluted indoor air or introducing fresh outdoor air, it can efficiently accomplish both tasks, contributing to a comfortable and healthy air environment.
3. The external rotor motor features high efficiency, low vibration, and low noise.
4. The ducted fan installation method, with mounting legs, is simple to install and allows for permanent installation in various ventilation systems.
5. The simple structural design facilitates maintenance, making daily cleaning, component inspection, and replacement easy, reducing ongoing maintenance costs.
